OUT OF STOCK 2023-04-05. Waiting to schedule machining new kits...
Dual nozzle head for pick and place machines. REFER TO THE LISTS BELOW FOR WHAT IS INCLUDED. Surface finish subject to change.
FULL KIT:
Full set of CNC MACHINED PLATES, Hardware, 2x high quality linear rails, 2x NEMA 8 hollow shaft motors, 1x NEMA 17 Z rotation motor, motor harnesses, inductive sensor, brass spur gear, 1/8" pins for locking the X axis belt in the tensioners.
PLATE AND SPUR GEAR KIT:
Includes all of the machined plates (9 including the two tensioner brackets) and the required spur gear. You will need to order the rails, motors, inductive sensor and hardware. See below for a list of the required parts to build the head (with buying references!).
(NEW!!) PLATE, SPUR GEAR AND HARDWARE KIT:
Includes everything in the Plate and Spur Gear Kit, as well as all the hardware (screws/ nuts/ pins) needed to assemble the head. Does not include components like the inductive sensor etc.

This is our dual nozzle pick and place head. NEMA17 Z axis motor, machined rack and pinion design, hollow shaft NEMA8 part rotation motors. This works perfectly with our high precision Juki Nozzle holders (See them here) and our new CP40 nozzle holders. See our other PnP accessories here.
NEW DESIGN IN PRODUCTION! Type II heads have been machined and tested. Much more compact and lighter than the previous version. 24mm nozzle to nozzle spacing. No more nut traps, all CNC tapped or thread-milled. Now the head runs the latest Smoothie version without modification (see here for the homing test: youtu.be/uEAuCsUzhdY).
Mounts on a MGN 12H (long) or MGN 12C (short) rail bearing block for single head installation. You can chain heads together (see images below) using the Linq plate (supplied if you order 2 or more heads) and you can either use 2x 12C (short) bearing blocks (one on each head) or bridge 2 heads together using a single 12H (long block). Single head requires 3 stepper drivers (so a typical 5 axis control board will work on a machine that uses 1 X motor, and 1 Y motor), or a total of 8 stepper drivers for a dual head setup that uses 1 X and 1 Y motor (2x 4 axis control boards).
All mechanical parts are the same so upgrading from the old style to new style just requires a plate kit (and the required hardware)!!

I could also probably do custom back plates for people looking to put this on a machine that doesn't have a 12mm linear rail on the X axis. Contact me for pricing.
Specifications:
- designed to mount to a standard 12mm linear rail (HIWIN with LONG block for example: MGN12H, Short block MGN12C).
Check out the head mounting drawing below for more details.
- 5mm hollow shaft for nozzle holder mounting.
- Each nozzle can drop down approximately 22.5mm from neutral.
- Homing is accomplished using an inductive sensor. See the homing tab for more details.
- Easy to modify the mounting plate for other systems (like openbuilds C beam, etc.)

Wiring the inductive sensor
NOTE:
As I made this, I realized I technically wired to the wrong Z endstop port. I wired to the max port when I am using home to min. It works and does not seem to matter, but you can wire to the min port, then change the gamma_min_endstop setting to 1.28! Either that or just connect and wire as shown below
The three wires of the inductive sensor can be connected directly to the smoothie endstop connector.

Configuring Smoothie
Smoothie config Z axis homing section example
openPnP configuration
The head uses an inductive sensor to home. When the head homes, the left and right carriages are offset about 14.4mm from each other. In order to level the two nozzles and reset the DRO to Z0, a special homing procedure must be used in openPnP:
In order to accomplish this, we must add some commands into the driver settings. In the machine setup tree navigate to: Drivers>gcodedriver>gcode>HOME_COMMAND
Copy the code below and paste it into the HOME_COMMAND section as seen above
Homing code
WARNING!
Some unexpected behavior has been observed when the machine is homed more than once (noted when using visual homing). It is recommended that you only home the machine once and if you need to home the machine again, then please restart your Smoothie board and openPnP. We will look into this further and report back.

We use the "special" PnP smoothie firmware found here: makr.zone/smoothieware-new-firmware-for-pnp/500/
The example config above is setup to use this, the main difference is that instead of extruders for the nozzles (E0 and E1), this firmware uses A and B rotational axis.
